STRUCTURAL GLAZING

Precision, Performance & Architectural Impact

Structural glazing is a modern façade engineering solution that delivers uninterrupted glass façades, sleek aesthetics and superior environmental performance. At Structura UK, we design, manufacture and install bespoke structural glazing systems for commercial buildings, heritage refurbishments and landmark developments across the UK. Our approach combines technical expertise, high-performance materials and careful project management to deliver façades that maximise natural light and meet stringent performance standards.

What Is Structural Glazing?

Structural glazing is a form of façade construction where glass is bonded directly to the building’s structural frame or a secondary framing system with high-strength silicone sealants and concealed fixings. Unlike traditional curtain wall systems that rely on visible mullions and transoms, structural glazing creates a flush, frameless glass appearance that is both aesthetically refined and functionally robust. The result is a clean, contemporary building envelope that achieves uninterrupted views, controlled daylighting and excellent environmental performance.

 

Typical applications include:

 

  • Glass façades and curtain walls with minimal sightlines
  • High-performance glazed office fronts
  • Atriums, retail façades and bespoke architectural glazing
  • Retrofit and heritage glazing where visual impact is key

How It Works

At Structura UK, delivering a flawless structural glazing installation involves a clear, collaborative process from initial design through post-handover support:

1. Project Initiation & Briefing

We begin with a detailed conversation to understand your design vision, budget and performance criteria.

 

2. Site Survey & Technical Assessment

A certified survey team visits your site to collect critical data required for precision engineering.

 

3. Design & Engineering

Our façade engineers create BIM/CAD models, load calculations, silicone specification and sealing details tailored to your project.

 

4. Material Selection & Detailing

Glass types, coatings, silicone grades, gaskets and structural supports are selected based on structural loads, thermal performance and aesthetic goals.

5. Manufacture & Prefabrication

Components are fabricated in controlled facilities, reducing site work, errors and installation time.

 

6. Installation & Façade Assembly

On-site glazing installation is managed by experienced teams, ensuring accurate alignment, sealing and safety compliance.

 

7. Performance Testing & Handover

Completed façades undergo rigorous leak testing, air pressure testing and final certification before handover and maintenance planning.

Frequently Asked Questions

What is the difference between structural glazing and curtain walling?

Structural glazing uses concealed fixings and silicone bonding for a flush glass appearance, whereas curtain walling uses visible aluminium framing components. Structural glazing delivers a cleaner aesthetic and higher perceived transparency.

How durable is structural glazing?

When designed and installed correctly, structural glazing systems withstand wind loading, thermal cycles and weather exposure for decades, backed by appropriate sealants and frame engineering.

What maintenance does structural glazing require?

Routine façade inspections, cleaning, seal integrity checks and periodic performance reviews are recommended to maintain thermal and weather performance.

How long does installation take?

Timelines vary, typically between 6–12 weeks for installation, but project size, complexity and site constraints can affect timings.

Do you provide performance testing after installation?

Yes. We conduct water penetration, air infiltration and structural checks as part of our final certification.

Is structural glazing suitable for listed buildings?

Yes. We specialise in heritage façade treatments that combine modern glazing performance with sensitivity to historic materials.

Can structural glazing improve a building’s energy performance?

Yes, with appropriate glass coatings, thermal breaks and sealing, structural glazing can support compliance with Part L Building Regulations and reduce operational energy loads.

The team worked tirelessly to ensure that the new materials used respected as far as possible the design philosophy of the original architects, and conserved the important aesthetic appearance of the building in line with Historic England’s approach to Constructive Conservation. The badly deteriorated concrete mullions and transoms of the glazing were replaced with steel and aluminium capable of supporting the weight of specially treated double glazed units and able to withstand the harsh weather conditions.
